Hi
I just finished this a few nights ago, this has taken several nights to do due to weather and false starts, it is 24x10 minutes Ha, 26x10 minutes OIII and 22x10 minutes SII. The seeing conditions were very poor for the SII data with some very thin misty cloud throughout the evening. This was taken with the Televue NP127is/FLI imaging system that I'm testing, this is set up on my Paramount ME with auto guiding taken care of by an Officine Stellare Falco guidescope and Starlight Xpress Lodestar camera. Image acquisition, guiding and stacking was done in Maxim DL5, the images were registered with Registar and processing was done with Photoshop CC.
The full size image can be seen at the following link

Thanks for looking
Best wishes
